The paid version (app) doesn't work. I reached out to a number of people who purchased it and they felt they'd been ripped off...
As for the add-on itself that's (as another review indicated) dead in the water...
Though not perfect, UDL Helper does work and is the best thing going these days...
As for the paid app that Dishita is selling, I woudn't pay a dime for it!

not sure about the paid version but this didn't work.

Just saying "Generating download link, pls wait" but nothing more happens.

No longer works and hasn't worked for months now. Others seem to be reporting that it works but it's totally broken for me

This app does exactly what it says it does and does it very well. I can heartily recommend it.

The updated app download works great! Your app has been so helpful over the years in backing up my work! Thank you so much for keeping this up! Very much appreciated!!!!

Love this ad-on. Hope it continues. Can't donate now but will later. The last 4 years has me counting dimes again.

Doesn't work for me either. FF up 2 date, v 134

Ich habe mir das neue add on herunter geladen und es funktioniert einwandfrei auf meinem mac (Ich arbeite noch mit Catalina). Ich kann dieses tool sehr empfehlen, bitte Herrn Disihita gerne auch sponsoren. Viele Grüße aus München!

it was fine, but now it doesn't work

Perpetually attempts to generates download link, unable to download.

Dosn't work
